You are awesome... Step by step... very nice.. No chance to beat u. I saw somany videos, but this is very clear explanation. Thanks for your hard working efforts.
Hello , i'm testing the code, however when i added the readPing function and recalled it again back above, it is showing me that the function is not declared in this scope , what could the problem be ?
yes that's it, moreover if it was a 2-wheeled car for example, there will be only one which will turn, with annoying parasites which will be generated by the Arduino board
I using this robot in my course. We are having trouble getting the motors to react, they don't rotate. The servo reacts correctly when we pass our hand in front of the ultrasonic but the motors do not rotate. We have triple checked the circuit and are fairly confident that is correct. Have measured the battery and we have 8.4 V at full charge.
The sensor shield is easy to use, but only the l298n motor drive, servo motor, and ultrasonic sensor are used here.Applying a sensor shield costs a lot of money. I didn't use it because it could be used for something else.
Thnx for the assemble video! I have a few problems. The car gets power by connecting it to my pc. Once it is connected, the servo moves once if i manually changed the position beforehand. Then the car starts driving straight and does not stop. The servo and sensor do nothing. Any ideas?
Hello, Can I use the same logic of car to design an robot who detects crack on railway track? If IR sensor senses obstacle then crack is not there and if Sensor does not finds obstacle then crack is there. Will it work, what modifications I need to do in code and circuit as well??
I have make the connection as it is as per circuit diagram but my car is not working only the light of arduino and motordriver is blinking but nothing is working.. Please help me i have to submitt my project day after tomorrow
I have two Lithium batteries (each is 3.2V and 1A) and I'll use them in series.. Is it okay? If yes can you tell me how to connect them. I also have one 18650 battery but I don't know if I can use different types of batteries. Can you help me please 😊
Should be connected in series.18650 Any type of battery can be used.7.4V can be provided when the battery is connected in series .Even three batteries can be connected in series.
I think I found my mistake. But I have one more question. I used 3 piece of 18650 battery so in my opinion the motor seems to be too "fast", how to reduce the speed of the motor?😅
Hello I made this as it you have said it's just I used a 4 cells battery pack and connected it accordingly to LM298 drive module as shown in circuit diagram. I also connected one 6V battery in Driver module using 5V supply and grnd supply. The car is operating at a very low speed and the sensor is not rotating I am not able to find a solution I have tried it ample of times
Maybe it works because the amperage in the powerbank is higher.Try connecting the powerbank. If the power goes out, only the ultrasonic sensor, arduino, servo motor will work. Motors will stop working.
♥️♥️please please replay ❤️❤️ Bro when I done this project servo motor and ultrasonic sensor were rotating properly. But now only wheels are rotating and servo motor is not working Also I checked each and every component all components are working separetely. Also all connections are ok. ❤️❤️Bro please reply what submit This in college♥️♥️
Hello, I have a problem when the car moving forward the right side DC motor move slow & sometimes not moving I need to move the tyre using hand then it worked but still slow but when reverse it worked. Can you help me? Thanks
Hey, my motors don't move at all. Mind helping me out? Standard there is a jumper on the ENA and ENB pins, so I did not touch them. The servo and ultrasonic both work and I think I did it the exact way like you did
Hi, I need your help. My motors do not work(I only have two motors). and i use two 3.7v li iron batteries just like the video, but it still don't work :( . My motor is not broken , i had test it before , the servo motor and sensor is working well , i can't find the problem with my car, can you help me :(
Bro... My motors are not running for some reason. If i connect the Arduino to laptop than it works. Is it power issue. How much power does it need to work properly??
L298 Module Features & Specifications: Motor Supply Voltage (Maximum): 46V. Motor Supply Current (Maximum): 2A. Logic Voltage: 5V. Driver Voltage: 5-35V.
I used a motor driver shield to my obstacle avoiding Robot. but it make a sound and gear motors doesn't work. but the servo works. can you please help me?
bro ,i did everything but car is keeping going backward without stop ,is it sensor problem or something else .my batteries are 2x 18650 2.7v i would appreciate it if you can help thank you
@@RobotLk yes sir now it is going forward without stop as the backward situation. what is your idea ? maybe sensor ? . im trying to solve this since a month
Hi! Thank you so much for the code. The car runs well, but when I tried to add a IR receiver or a sound sensor, it kept giving me "readPing was not declare in this scope". I made sure I have a newping libary installed. Do you have a phone number I can each you out? Thank you for the help!
